Output frames per second to test map

[dave.tyner]

Hi, I am working with a very large (10 square miles) scene. I am trying to get an idea of how each imported object is effecting my performance. I know I can run the application.statistics command to see the FPS in the console. How can I continuously display only the FPS stats on my test level? Thanks!

You can use "perfhud artist" to show fps. I'm not sure we have a command to show only the FPS. I will look into it. For now, you could just run Fraps when running your game, it will show FPS in the corner window.

Fantastic, thank you Dan!

Is it possible to show a performance overview in a deployed executable (windows platform)?

[dan.matlack]

I'm not sure as I've never tried that specifically. I will ask the engine team. The perfhud may be wrapped up in engine code and not specific to your deployed project. You can of course always write your own inside your project to be printed to screen at your discretion.

Re perfhud: As long as you are running a debug or development (dev) compiled executable the perfhud will work on all targets. They will only show meaningful GPU timings on PC & consoles though.

Excellent, how will i access that when running? or is i something I need to set up before I export?

@mmartin256 You will need to write a custom flow node or put this in lua and then call it on a key press, or all the time, in your compiled executable:

s3d.Application.console_command("perfhud", "artist")
